These set-ups are aids for normal racers like us who want to share or get input from other racers, from pros or regular schmoes. Whether or not it makes it better is all up to the driver and the end result of that set-up. At what extent Xray goes through for all it's customers to provide a database of set-ups and tips is still leaps and bounds for other manufacturers out there. It may not thrill you but there are others just like me who are glad to know that there is a wealth of information at the tip of their fingertips. Whether they use it or not is there perogative.
So like i said....show me another company close to this.
